ATTACHMENT FOR ELECTRIC GHANDELIERS.

Specification of Letters Patent.

Patented Sept. 9, 1913.

Application filed December 2, 1912. Serial No. 734,496.

To all whom it may concern:

Be it known that I, HENRY LEIK, a citizen of the United States, residing at Seattle, in the county of King and State of WVashington, have invented certain new and useful Improvements in Attachments for Electric Chandeliers, of which the following is a specification. V

This invention relates to devices for attaching chandeliers to ceilings and more particularly to improvements in the appliances shown and described in U. S. Patent No.1,014,063, issued to me November 12, 1912.

The object of the present invention is the perfecting of such devices by the provision of an adjustable casing or juncture box for the wire connections in the ceiling to protect the latter from danger of being ignited by crossed wires or otherwise.

The invention is illustrated in the ac companying drawings, wherein- Figure 1 is a transverse vertical section of a junction-box and chandelier supporter arranged for an electric light fixture. Fig. -2 is a similar view of the invention adapted for use with a combined gas and electric light fixture. Fig. 3 is an underside view of one of the box elements.

Referring to the drawings, 5 denotes a piece of timber, or header as it is called, which is fixedly secured to the floor joists, such as 6, and constitutes a part of the floor or ceiling structure. The under surface of said header is disposed to be flush with, or in the same plane with the lower edges of the joists and the laths, indicated by 7, which carry the plastering 8 are nailed to the same.

In carrying out my invention, I provide a junction box comprising complementary cylindrical members 9 and 10. The lower of these, 9, consists of a circular wall 11 ofa depth equal to the combined thickness of the lath and plaster of the ceiling and is secured to the underside of the header 5 by screws 12 extending through apertured lugs 13 extending outwardly from the wall 11 as shown in Fig. 3. Centrally of the wall 11 and connected thereto by radial arms 14 is a boss 15 having a screw threaded hole extending axially therethrough.

Extending circumferentially about the lower edge of wall 11 is a flange 11 which serves as a shoulder for supporting the plastering thereabout. The other member, 10, consists of a circular wall 16 of less diameter than the internal diameter of the wall of the other member. The member 10 is of greater depth than the thickness of said header so that it can be inserted through a hole provided in the latter and extend for a distance into the member 9 thus affording an overlap between the two members. The member 10 is closed at its top by a plate element 17 and is provided about its periphery with apertured lugs 18 to receive screws 19 for fastening the member to the header.

Centrally of the plate element 17 is a portion 20 of less thickness than the surrounding portion and which may be knocked out by a blow from a hammer when an opening, as 21, is requisite for a gas pipe 22, as shown in Fig. 2.

Openings 23 are provided in said plate element to receive tubes 24 of porcelain, or other electrical insulating material, through which extend the circuit wires 25. i As illustrated these wires are further protected by tubes 26, such as of rubber.

For supporting a chandelier arranged for electric lights only, the fixture pipe 27 thereof is screwed into a bushing 28 provided with both internal and external screw threads and the bushing, in turn, is screwed into the boss 15.

WVhere a combined electric and gas fixture is used, the gas pipe 22 extends through the referred to opening 21 provided in plate element 17 of member 10 and also through the boss 15 of member 9.

Tapering pieces 29 are inserted in the space surrounding the pipe 22 where it passes through the boss and by such devices the fixture is not only secured to the member 9 but may be regulated to assume a vertical position, which is of importance where the gas fixtures are connected to a gas-supply pipe.

30 represents the so-called canopy which is utilized for ornamental purposes at the upper end of the chandelier.

The invention is extremely simple, is readily applied, and not only serves to safeguard the woodwork of the ceiling from fire emanating from the electric wires, but also furnishes a gage whereby the plastermg may be laid onto an even surface coextensive with the underside of the member 9 While the plastering is supported about the latter by means of the protruding flange 11 What I claim as my invention, is Means for attaching electric-light chandeliers to ceilings comprising an outlet box formed of a relatively short and a long section, said shorter section to lie flush with theceiling, a header-block provided With an opening centrally therethrough, the

short section extending through the ceiling to a point at the base of said header-block, lugs carried by the outer end thereof and engaging the bottom face of said headers block constituting means for securing the same thereto, the longer section adapted to openings therein to receive the Wires and support an electrolier.

Signed at Seattle, Wash, this 19th day of November, 1912.
